Help me something about GNU Octave

[Johann Cohen-Tanugi]

hello,
by sheer curiosity I gave a shot to this command :

  [u, s, v] = svd (rand (10000, 10000));
and I actually get :
octave:1> [u, s, v] = svd (rand (10000, 10000));
error: memory exhausted or requested size too large for range of Octave's index type -- trying to return to prompt

any idea what could go wrong?  am on a linux FC7 laptop, and octve is built from cvs source :
octave:2> version
ans = 3.0.0+

best,
J.
